Documents obtained by National Security Agency leaker Edward Snowden and reported on by The Washington Post reveal a massive $52 billion so-called "black budget" for the current fiscal year. They also show how the U.S. used virtually every tool of surveillance to find Osama Bin Laden. CBS News senior correspondent John Miller, a former deputy director of national intelligence, discusses the documents and what they divulge about U.S. operations.
